Last weekend, Skrillex joined Diplo on Diplo & Friends for a two-hour Jack Ümix. The mix featured a ton of unreleased music, but two tracks stood out in particular. Both of the tracks are unreleased Jack U tracks, and they each feature huge collaborators.

The first track, "Febreze," features star rapper 2 Chainz. Listen to the song below.

The other standout track does not have a name yet. Snails joined Skrillex and Diplo on this one, and it's absolutely huge.
